Paper Abstract

An original photonic crystal fiber based sensing head is proposed for strain measurement. The sensor comprises a Hi-Bi PCF sensing head to measure in reflection using polarimetry. A background study of the sensing head polarization state signals is conducted utilizing an optical backscatter reflectometer. Using a more accessible set up, one of the Hi-Bi PCF polarization signals is isolated allowing to accurately measure strain variations. In-reflection polarimetric strain sensing is obtained with a sensitivity of ~7.6 dB/1000μm and with the breakage point at 5500 με.
